SUBMARIIN'E GUN.

Specification of Letters Patent.

Patented Aug. 12, 1919.

Application filed May 24, 1916. Serial No. 99,672.

To all whom iii-may concern:

Be it known that I, HALVOR OLSEN EIANE, a

citizen of the United States, residing at Detroit, Harbor, in the countyof Door and State of Wisconsin, have invented a new and useful SubmarineGun, of which the following is a specification.

My invention relates to improvements in submarine guns, in which thechief objects are, first, to mount the gun in the interior of asubmarine vessel; second to provide the n with such means that it can befired, as well when the submarine, vessel is slightly submerged, as whenon the surface of the water.

I attain these objects by the use of a gun, having a novel mounting, andoperating mechanism, hereinafter more fully described, and claimed,having reference to the accompanying drawings, in which Figure 1,represents a side view of the gun in its mounting, and with itsoperating mechanism. Fig. 2, represents a sectional side view of thegun, showing how shell and powder charge are held in place in thechamber of the gun. Fig. 3, is a rear view of the recoil cylinders, withsegmental runners. Fig. 4, is a sectional rear view of the pivotalmounting for the muzzle end of the gun. Fig. 5, is a side view of theholder of the powder charge. Fig. 6, is a side view of the loadingmechanism for the gun. Fig. 7, is a top view of a submarine. vessel,showin location of the gun. 1, in Fig. 1, is t e gun barrel. 2, are therecoil cylinders. 3, arethe segmental runners. 4, is the circular track.5, are the rollers, which are placed between the segmental runners 3,and the circular track 4. The globe-headed sleeve 6, is movably fittedinto an aperture 7, with globular cavity, which constitutes the pivotalmounting on the muzzle end of the gun 1. When the gun is ready to befired, the crank handle 8, is given a complete turn, this movement alsoturns the cam 9, which first disengages the pawl 10, and then raises thelever 11, which in turn moves the reversing valve 12, into positionwhich starts the engine 13, to revolve in the right direction; the worm14, which is secured on the crank shaft 15, turns the worm wheel 16,which is secured on the shaft 17. The shaft 17 passes through thebearing 18, and the stufling box 19, and carries on its upper end abevel gear 20,

which engages the bevel toothed sector 21, which is an integral part ofthe closure 22; and at the same time the closure 22, starts to open, theworm 23, turns the worm Wheel 24, which is connected to the valve 25,and causes a simultaneous opening of said valve, and said closure; and astrong flow of compressed air or gas, from a suitable reservoir (notshown) passes through the pipe line 26, and up through the passage 27,in the wall of the aperture 7, (shown in Fig. -4,) and into the circulargroove 28, in the globe-headed sleeve 6, where the air flows around thegun barrel 1, and up through the narrow space between the gun barrel 1,and the inside wall of the globe-headed sleeve 6, forming a protectivewall of fast flowing air, against inrush of water into the bore of thegun barrel 1. There will also be an additional set similar to 23, 24,25, and 26, leading to the passage 29, and into the circular groove 30,from which the air flows into the passages 31, (shown in Fig. 2,) andout through the bore of the gun barrel also f th urpose of keeping waterout of the bore of the gun barrel 1. \Vhen the closure 22, has aboutreached its full opening, the arm 32, on the worm wheel 24, closes anelectric circuit (not shown) which fires the gun. As the gun barrel 1,recoils, the air passages 31, will automatically be closed, and theslotted end of the lever33 which is connected to the gun barrel 1, willon its return movement to normal position, through the spring actuatedpawl 10, engage the lever 11, which is connected to the reversing valve12, and thus reverse the engine 13, which closes the closure 22, andshuts off the air valve 25. There will be two sets like 14, 15, 16,7717,77 18, 19,77 20,77 ald 21 77 The two worms 14, and 23, willpreferably be double threaded in order to increase the speed of the wormwheels 16, and 24. A suitable indicator may be connected to the shaft 17so as to indicate the position of the closure 22. When the gun is to beloaded, the following operations take place: The lever 34, which isvconnected by reach rod and rocker arms, to the reversing valve 35, onthe engine 36, is worked, which starts the engine to revolve inthe rightdirection, and the rotary movements of the crank shaft 37, aretransmitted through the worm 38, engaging the wormwheel 39, which issecured on the shaft 40; the shaft 40 passes through the bearing 41, andis connected by the universal joint 42, to the threaded screw 43, whichengages the threaded eye bolt 44; the latter being tu rnably fitted intothe rear end of the runners '3', and as there will be two sets like 38,39,77 40,37 4 1, 42, 4 3, 44, it will be seen that the gun 1, can bemoved by its rear end support to the l mit of its travel toward the door45. After the door 45, has been opened, the hinged loading spoon 46, israised into position, and a shell placed on the spoon, from which pointthe loading arm 47, raises the shell into the chamber of the gun 1'. Theshell is then rested on two spring moved check pawls, located on eachside of the loading spoon 46, shown by dotted lines 48. The loading arm47, is then brought back to its starting point, and the extension ram49, swung 'byhand under the shell, which is then forced into its placein the chamber of the gun 1; and an expansion ring 50, on the shell 51,expands into a groove 52, (shown in Fig. 2,) which holds the shell 51,in place. The powder charge, which preferably will be kept in a suitablecanvas bag of the required size, will be loaded into the chamber of thegun 1, in the same manner as the shell. An iron bar 53', provided at itslower end with a flange 54, and at'its upper end with expansion barbs55, will be placed in the center of the powder bag, and the expansionbarbs 55, expand into a recess 56, on the rear end of the shell 51, thusholding the powder charge in place in the chamber of the gun 1. Theloading arm 47, will be operated by compressed air'moving a piston in ahinged cylinder, and controlled by a hand moved valve. The engines 13,and 36, will also be operated by compressed air. As the gun 1, will beplaced in a water tight compartment, in order to better insure thesafety of the vessel, which carries said gun, it is therefore necessaryto provide means for ascertaining the angle of the gun, on the outsideof said compartment, and for this means, the forked connecting rod 57,transmits the angular movements of the gun 1, from the globe-headedsleeve 6, to the crank lever 58, which is connected to the pointer 59,from which reading may be taken on the graduated sector 60. Theconnecting rod 57, also keeps the globe headed sleeve 6, from turning inthe aperture-7. The gun 1, will be provided with a suitable counterweight, (not shown) and attached to the screw 61 which is threadedopposite to the screw 43, object being to keep the submarine vessel onan even keel. If it should be desired to remove the load. from the gunwithout firing, the following means may be employed. By uning the flange54, the powder may be removed; and by providing four or morelongitudinal grooves in the chamber of the gun l, slightly deeper thanthe groove 52, through which wedges may be inserted, and the expansionring 50, disengaged from the groove 52, and the shell removed. The gunwill be mounted in the middle of a submarine vessel, and centrallybetween two hydroplanes 62, and 62, of suflieient strength to bear thestrain produced by the recoil, when the gun is fired. The submarinevessel which carries the gun will be provided with suitable trimmingtanks, fore and aft, as well as on both sides for the purpose of keepingthe submarine vessel on an even keel, and also tanks for compensatingweight discharged by the gun. The gun may be mounted single as shown inthe accompanying drawings, or in pair side by side. I do not wish to beunderstood to limit my invention to the exact description, and drawings,as herein given, as many changes can be made without departing from theprinciples involved.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is 1.
